Arc'teryx Nuclei Pant Men's

Light, packable, and built for belays, or anyplace exposed to biting cold, the Nuclei provides warmth that frees you to focus on your task. 80g Coreloft™ Continuous insulation goes from waist to knee, with 60g at the lower leg to balance appropriate warmth and light weight. The light, tough Arato 15 fabric blocks wind, and GORE-TEX reinforces the seat and knees. Full separating side zips make on-and-off easy - even on hanging belays - and an accessible thigh pocket doubles as a stuff sack.
